To all whom may concern: also provided with a keyway 11, opening out Beitknown that I, I-IYSON BOYLES,acitizen on the Youtside thereof andregistering with of the United States, residing at Janelew, in thekey-slot in the inner cover-plate.

This pin serves as 6o 1o efficient device of thischaracter in which the a pivot on which the har-operating disks, to barscan be operated from either inside or be hereinafter described, aresupported and outside the door by means of a key and havalso as a guidefor the key which operates the ing automatic devices to lock the bars indisks.

Any arrangement is inclosed in acasing 6, which is partiallylet of wards may be formed on the outer faceof into the dooron its innerside,as clearly shown each disk, such asshown at 23 in the drawin Fig. 2. The casing consists of arectanguings,and these wards may be varied on dif- 95 45 lar frame 7, adividing-plate8, secured within ferent locks, as will be readily understood.

the frame in any suitable manner to divide In order to lock the disks atthe extremiit into two substantially equal compartments, ties of theirmovement, I provide a lockingand cover-plates 9, which are secured tothe plate 24, which extends through the slot 14 opposite edges of theframe 7 in any approved in the dividing-plate 8 and across the periph-10o 5o manner. Each cover-plate is provided with cries of the disks 1Gand 17, and the lower a key-slot, (indicated by 10,) and the door isedge of this plate is adapted to seat in the notches 2l. Thislocking-plate is provided at its upper edge with a slot 25 to receivethe dividing-plate S and permit the locking-plate to have verticalmovement. Anysuitable devices may be employed to hold the lookingplatein the slot and guide it in its vertical movement, such as pins 2G,which are shown on one side of the plate S in' the drawings, or flanges27, which are shown on the other side of the plate 8, such devices to besecured to the locking-plate in any suitable manner to engage theopposite faces of the dividingplate. A pair of spring-arms 2S aresecured to the locking-plate at cach end thereof, and to the lower endof the arms bars 29 are secured to extend at an angle therefrom inopposite directions. Each of these bars is provided With a lug 30, whichprojects in the path of travel of the key to be engaged thereby. Theselugs are so arranged that the key will engage them just previously toengaging the pins 22, which project outwardly from the disks.Bow-springs 3l are supported in the upper end of the casing on each sideof the dividing-plate and engage the upper edge of the locking-plate 24Eto normally hold it in engagement with the disks.

Assuming the parts of the locking mechanism to be in position shown inFig. 8, the locking-bars 4 will be in engagement With the keepers andthe door be securely fastened. Assuming now that it is desirable tounlock the bolts from the outside of the door, the key Will be insertedthrough the keyway ll and the key-slot in thcinner cover-plate andturned to the right. This will cause the key to first engage the lug 30on the bar 2D, which will have the effect of lifting the lockingplateout of engagement with the notches 2l in the disks on both sides of thedividingplate, and the further movement of the key Will cause it toengage the pin 22 on the disk 16, and just as soon as the disk begins toturn on the pin 13 the key Will pass out of engagement with the lug 30and the boW- spring Will return the locking-plate into engagement withthe periphery of the disks. The disks can now be turned until the pinsor rivets 18, which started from one end of the slots l5, will beengaged With the opposite ends of such slots, when the further movementof the disks will be prevented. As soon as the disks stop the othernotch 2l will have been brought below the lockingplate S and the latterivill be forced into it by the action of the 'bow-springs 3l, and thedisks Will then be locked against rotary movement until thelocking-plate is again released to Without departing from the spirit orsacrificing any of the advantages of this invention.
